Mateo Joseph arrived at Elland Road in the opening week of January, but turned out to be Leeds United's solitary January addition in the winter transfer window.
The 18-year-old has integrated with the U23 setup following his permanent transfer from Espanyol, and in a bid to build match fitness is featuring for the U18 side, too.
Joseph was left out of regular action at his previous club in the months preceding his Leeds move, instructed to train alone with the understanding he would be moving on in January.
